Problems solved by technology

[0006] In this case, how the BS schedules the frames for the MS to start receiving data on the Secondary carrier is a big problem, because the MS closed the receiver and did not send a CQI report before this, so the BS does not know the Secondary carrier. What kind of modulation and coding method is used for the frames received at the beginning

Embodiment Construction

[0032] The embodiment of the present invention proposes that a terminal sends a CQI report on the carrier only when the secondary carrier receives data, and at other times, the terminal can choose to turn off the receiver and not send the CQI report, thereby saving the terminal CQICH overhead on the secondary carrier. In this case, the method for the terminal to report the channel quality information of the secondary carrier through the basic carrier achieves the effect of saving channel resources while maintaining information scheduling

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the...

Abstract

The embodiment of the invention discloses a method, a device and a system for scheduling information. The method comprises the following steps of: sending and reporting a notification message of secondary carrier channel quality information to a terminal through a main carrier or a secondary carrier; instructing the terminal to send the secondary carrier channel quality information through the main carrier or the secondary carrier; receiving the secondary carrier channel quality information sent by the terminal through the main carrier or the secondary carrier; and determining a scheduling mode of secondary carrier receiving/sending data according to the secondary carrier channel quality information. The method, the device and the system achieve the effects of keeping information scheduling and saving channel resources at the same time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information scheduling method, device and system. Background technique [0002] CQI (Channel Quality Indicator, Channel Quality Indicator) is the information that the terminal feeds back channel quality information to the base station. In the IEEE 802.16e standard, the base station will periodically allocate uplink system resources dedicated to sending CQI feedback information to the terminal. The terminal Use this resource to send CQI feedback information. [0003] In a multi-carrier system, there can be one or more primary carriers, which can transmit control information and resource assignment information, and can also transmit data. At the same time, there are one or more secondary carriers in the system (Secondary carrier), this type of carrier is mainly for the purpose of transmitting data, but it can also transmit information such as control signaling or...
